- No loft tank or cylinder
- Compact — ideal for flats

System Boiler
Works with a hot water cylinder but doesn\'t need a cold water tank in the loft. Great for higher hot water demand.

- No cold water tank needed
- Compatible with solar thermal
- Faster installation than regular
Best for: 2–3+ bathroom homes, larger families
Regular Boiler
Traditional setup with both a hot water cylinder and a cold water tank. Best for homes with existing pipework.

- Ideal for older properties
- Good for low water pressure areas
- Can supply multiple bathrooms
Best for: Older homes, low water pressure, existing cylinder setups
